Holographic display and intelligent interactive teaching integrated system

Abstract

The invention discloses an integrated system of holographic display and intelligent interactive teaching, which comprises a signal processing system, a display processing system and an output system. The signal processing system includes an imager, a controller, a light sensor, a digital signal processor, a display interface, an image divider, and two image modulators. The display processing system includes an operating system, a stereoscopic rendering engine, and a high-definition graphics card. The signal processing system mainly completes the data collection and processing of plane and stereoscopic images, works together with the display processing system, and completes depth information positioning and stereoscopic rendering through two synchronous steps. The output system includes a projector, The optical path controller and display screen can complete the switching between stereoscopic images and planar images. The invention simplifies the 3D holographic imaging process, accelerates the holographic processing of the planar image, can complete the free switching between 2D and 3D holography, and at the same time integrates with the function of the intelligent planar electronic blackboard, enriches the teaching methods, arouses learning interest, and achieves better teaching effects.

Description

technical field [0001] The invention relates to the field of teaching integration systems, and more specifically relates to an integrated system for holographic display and intelligent interactive teaching that can be widely used in the teaching field. Background technique [0002] The introduction of intelligent teaching equipment has brought about tremendous changes in teaching quality and teaching methods. Emerging technologies have played a vital role in this. Teaching equipment has begun to develop in the direction of intelligence, and the application of smart blackboards and smart whiteboards is increasing. In general, in the future, expanding the multi-functional integrated teaching system will become an inevitable trend of school teaching upgrading and student quality development. [0003] At present, first, teaching generally relies on graphic display, which is not conducive to students' full understanding of what they have learned, the formation of spatial thinking...

AI Technical Summary

Problems solved by technology

[0003] At present, first, teaching generally relies on graphic display, which is not conducive to students' full understanding of what they have learned, the formation of spatial thinking and image thinking, and is also not conducive to teachers' implementation of teaching. During the teaching process, more time will be spent on graphic display and explanation, affecting Teaching rhythm; second, 3D holographic displays are generally used for exhibitions, and holographic displays are generally set up separately, which takes up a lot of space and is not easy to move

Using optical refraction, the imaging quality will be affected to a certain extent, and the use of holographic imaging requires the use of matlab and other languages, and a large number of data sampling calculations to convert the real object into a holographic image. The process is cumbersome and professional, which is not conducive to the use of teaching resources. Independent expansion; third, the 3D holographic display function is single, and it has not yet been used interactively with other intelligent teaching functions, which reduces the convenience and interactivity of teaching
